Pulling Numbers Apart
divisibility · using factors of a product to identify divisors
Use the factors used to create a product to determine which numbers divide the product evenly.
Pulling Numbers Apart is a Grade 4 divisibility investigation that starts with a large product and asks students to reason from its factors. After multiplying numbers such as 35, 24, and 44, students use what they know about those factors to decide which values from 2 through 12 must divide the product evenly. The emphasis is on structure, not repeated long division.
Use it when students are learning divisibility and factor relationships. Ask students to justify each divisor by tracing it back to one of the original factors or its factorization.
